Creating a Solid for topography coordinates

It is not a new topic.
But I am not able to fix my problem.
Can someone kindly help me on it.
I have coordinates (x,y,z), imported from Autocad to excel.
I want to create a solid topography.
I am very new to revit, dynamo world

hi,
try to use your point to a surface by NurbSurface.byPoints, and get another surface whitch is the base (floor ) , and use Solid.ByLoft node

I think the Solid.ByLoft only accepts curves as inputs. If that is the case you can use a Surface.PerimeterCurves node, and Surface.ByLoft node, and a Solid.ByJoinedCurves node.
